WALLED SHEET-METAL STRUCTURE.

Specification of Letters Yateiit. Patented luay 30, 1911.

Application led ctober 19, 1909.: Serial No. 523,513.

To all whom it may concern: f

Be it known that I, PETER M. WEGE, a citizen of the United States, residing at 'lVIariett-a., in the county of Washington and State of Ohio, have invented a certain newTv and useful `lmprovement in `Walled Sheet Metal Structures, of which the following is a specification.

The objectof this invention is to provide an improved construction of cabinet, safe or other walled structure in Which'the parts can be economically manufactured and quickly and securely assembled.

The invention is embodied in the const-ruction herein shown and described and then particularly pointed out in the claims.

ln the accompanying drawing: Figure 1 is a front elevation of a safe or cabinet containing the invention. Fig. 2 is a horizontal section on the line -w Fig. 1. Fig. 3 is a vertical section on the line 'yr-y Fig. 2. Fig. t is a vertical section on the line z-z Fig. 1. Figs. 5 and A6 are a plan and section respectively on a magnified scale illustrating the catches.

The parts are constructed chiefly of sheetA metal. Each Wall, as Well as the door, is

' rectangular' in outline, and as each is con- 'enfui lo the inner Sheet.

strncted in its body in substantially the same way, a description of Aone will sullice for all. The inner member (3' is formed of a rectangular piece of sheet metal slit or cut out at its tour corners and bent up at the margins, as seen at 7, to stand at right angles to the body of the sheet` thereby forming a shallow box-like structure. Each of the four margine or flanges 7 is then slit with a small slit and pressed out to forni a suitable number of catches 8 with their straight shoulders at il presented toi-:ard the plane ot the bodyv of the sheet.

'lhe outer sheet 10 is in form, generally speaking. similar to that ot the inner one eX- cep'i; .hal. it is of slightly larger arca. The margins ol' the. outer sheet. are. bent to forni, first, a llange 1l standing at right angles to the body ot the sheet and then from thisv an inwardly ,-xl'cnding flange l2 rl`he ends of the flanges ll and l2 at the corners ol lhe .en -et are .ewnred together in any suitable nninnei' or. as iwlore deseriliied. with rofl-i'- 'l"he sztrufyinic ihns just desi'i'ibcd rvs nblcs the lid of' a box, except that il has the flanges 12. The

flanges 11 are preferably of such depth thatJ the flanges 12 can be sprung over the catches 8 with the edges of the flange 7 abut-i ting or nearly abutting against the outer sheet 10.` The outer member is applied to the inner one in very much the manner in which a lid is 'applied to its box, except that considerable pressure may be necessary t0 cause the ange 12 to spring over the catches 8. The flanges v7 containing said catches 8 may be such as to yield somewhat in this operation.- When the tivo parte or members' of a Wall are thus connected they are effectively secured together.

In constructing a cabinet, safe or other similar Walled structure havingthree vertical walls, a top, a bottom, and a door as shown, the inner sheets of the vertical walls and top and bottom are preferably alone first secured together by bolting with bolts and nuts 13 to form eornersalong horizontal lines at the bottom and top, and'vertical eorncrsalong vertical lines at the back so as to leave the catches S exposed and in position to catch the flanges 12 ol the outer 'The member constituting the door can be hinged at 14 and the door can be provided with an ordinary knob 15 for operating it. The door can also be equipped with suitable locking devices (not shown) as may be desired.

The walls and door can be lined or filled with asbestos 2O or otherheat-resisting or retarding material. and they can be. braced or reinforced by ,stripsI of metal 1G set or secured lmlvreen the walls :is best seen in Fig.

then the walls are put together as particularly proposed, the braces 16 should be inserted before the lid-like members are applied.

lt will be observed that a safe, cabinet or other walled strife( nre. constructed :awarding to this invention presents a neat. chaste appc:ii'ance,Witli n1t unsightly excrescences. lt

van be provided with ornamental lop and bulloni moldings or pieren. as seen at 17 and l5: and casters as' at lil can be added.

l`.1e invention is not limited in ilsl use. to eabiuets or safes, but ean be employed with advantage in other structures, asflfor cX- ample in sectional book cases, letter files,

etc. Nor is the invention limited to the forms ot' the parts shown.

In an application tiled September 27th, 1909, S. No. 519,666, I have claimed a Wall unit according to the present invention.

What l claim is:

l. A 'walled structure comprised of a plurality of shal` wv box-like sheets or members provided with catches7 said members being united to form a chamber with the catches at the exterior, and e plurality of lid-like covers for external application to said boxlilce members provided with flanges tO engage the catches ot the seid boxdilte members.

. A v: lled structure comprised of a plu ralitvv of shallow boxlilie sheets or members provided with catches, said members unlted to term a chamber with said catches at the exterior, and a plm'alit)i ot lid-,like covers i for external application to said box-like y members having mani lianges with mturned margins or supplemental fianges to engage the catches of the box-like members. v

3. A walled structure comprised of shallow box-like sheets provided with catches, and lid-like covers for-.said sheets provided with flanges to engage the catches or' the box-lilre-slieets, and concealed devices unitingsr said Walls. y

4. A walled structure comprised of interior shallow'boxdike sheets provided with catches, and lid-like exterior covers for said sheets provided with anges to engage the catches of the box-like sheets, and concealed fastening devices securing the said boX-iilre sheets together.

5. A- walled structure comprised of a plurality of shallow box-like sheets or members provided with catches, said members united to 'form a, chamber with said catches at the exterior,` and a plurality of lid-like covers tor external application to said box-like members having main flanges with inturned margins or flanges to ei-igage the catches ot' the box-like members, the main flange of one ot the lid-like members abutting against the inturned margin of an adjacent lidflilte member, ysiibslantially as shown and de scribed.
